A Study on the Mode of Recurrence in Cases with Esophagectomy and Extensive Lymph Node Dissections

In cases with thoracic esophageal cancer, postoperative recurrence at the posterior mediastinum and the neck are frequently observed as well as metastasis in distant organs. Extensive lymph node dissection procedures have been developed and applied in cases of thoracic esophageal cancer for these 8 years in Japan, with the expectation that a decrease in the rate of recurrence in the neck and the mediastinum would occur. In this paper, the rate and mode of recurrence among patients with thoracic esophageal cancer who underwent esophagectomy with extensive lymph node dissection at our hospital were studied. It was expected that the results would yield improved indications and postoperative care of this type of patient.

Superficial depressed type of esophageal cancer radiological characteristics and their clinical significance.

表在陥凹食道癌36例のX線像を分析し, 4型に亜分類し, その臨床的意義を検討した.陥凹Iは平滑な隆起の表面に淡い綿雲状のバリウム斑として陥凹が描かれるもので, 全例が早期癌で予後も良好であった.陥凹II-1は平滑な周堤をゆうするもので, 混合型の1例を除き早期癌であった. 脈管侵襲を有する症例2例で再発がみられた.陥凹II-2は不整像の強い周堤を有するもので, すべての症例に, リンパ節転移がみられ, 最長生存期間も2年6ヵ月で, 予後は悪い.陥凹IIIは周堤がないか, わずかに認められるもので, 表在平担型との境界域の浅いもの, 微小癌以外はリンパ節転移を認め予後も悪い.
